* [libata] pata_it821x: fix warningJeff Garzik2008-08-22

* pata_it821x: Driver updates and reworkingAlan Cox2008-07-31
| | | | | | | | | | | | | | | | | | | - Add support for the RDC 1010 variant - Rework the core library to have a read_id method. This allows the hacky bits of it821x to go and prepares us for pata_hd - Switch from WARN to BUG in ata_id_string as it will reboot if you get it wrong so WARN won't be seen - Allow the issue of command 0xFC on the 821x. This is needed to query rebuild status. - Tidy up printk formatting - Do more ident rewriting on RAID volumes to handle firmware provided ident data which is rather wonky - Report the firmware revision and device layout in RAID mode - Don't try and disable raid on the 8211 or RDC - they don't have the relevant bits Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

* libata: rename SFF functionsTejun Heo2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SFF functions have confusing names. Some have sff prefix, some have bmdma, some std, some pci and some none. Unify the naming by... * SFF functions which are common to both BMDMA and non-BMDMA are prefixed with ata_sff_. * SFF functions which are specific to BMDMA are prefixed with ata_bmdma_. * SFF functions which are specific to PCI but apply to both BMDMA and non-BMDMA are prefixed with ata_pci_sff_. * SFF functions which are specific to PCI and BMDMA are prefixed with ata_pci_bmdma_. * Drop generic prefixes from LLD specific routines. For example, bfin_std_dev_select -> bfin_dev_select. The following renames are noteworthy. ata_qc_issue_prot() -> ata_sff_qc_issue() ata_pci_default_filter() -> ata_bmdma_mode_filter() ata_dev_try_classify() -> ata_sff_dev_classify() This rename is in preparation of separating SFF support out of libata core layer. This patch strictly renames functions and doesn't introduce any behavior difference. Signed-off-by: Tejun Heo <htejun@gmail.com>
* libata: stop overloading port_info->private_dataTejun Heo2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | port_info->private_data is currently used for two purposes - to record private data about the port_info or to specify host->private_data to use when allocating ata_host. This overloading is confusing and counter-intuitive in that port_info->private_data becomes host->private_data instead of port->private_data. In addition, port_info and host don't correspond to each other 1-to-1. Currently, the first non-NULL port_info->private_data is used. This patch makes port_info->private_data just be what it is - private_data for the port_info where LLD can jot down extra info. libata no longer sets host->private_data to the first non-NULL port_info->private_data, @host_priv argument is added to ata_pci_init_one() instead. LLDs which use ata_pci_init_one() can use this argument to pass in pointer to host private data. LLDs which don't should use init-register model anyway and can initialize host->private_data directly. Adding @host_priv instead of using init-register model for LLDs which use ata_pci_init_one() is suggested by Alan Cox.

* libata: make ata_pci_init_one() not use ops->irq_handler and pi->shtTejun Heo2008-04-17
| | | | | | | | | | | | | | | | | | | ata_pci_init_one() is the only function which uses ops->irq_handler and pi->sht. Other initialization functions take the same information as arguments. This causes confusion and duplicate unused entries in structures. Make ata_pci_init_one() take sht as an argument and use ata_interrupt implicitly. All current users use ata_interrupt and if different irq handler is necessary open coding ata_pci_init_one() using ata_prepare_sff_host() and ata_activate_sff_host can be done under ten lines including error handling and driver which requires custom interrupt handler is likely to require custom initialization anyway. As ata_pci_init_one() was the last user of ops->irq_handler, this patch also kills the field. Signed-off-by: Tejun Heo <htejun@gmail.com>
* libata: implement and use ops inheritanceTejun Heo2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libata lets low level drivers build ata_port_operations table and register it with libata core layer. This allows low level drivers high level of flexibility but also burdens them with lots of boilerplate entries. This becomes worse for drivers which support related similar controllers which differ slightly. They share most of the operations except for a few. However, the driver still needs to list all operations for each variant. This results in large number of duplicate entries, which is not only inefficient but also error-prone as it becomes very difficult to tell what the actual differences are. This duplicate boilerplates all over the low level drivers also make updating the core layer exteremely difficult and error-prone. When compounded with multi-branched development model, it ends up accumulating inconsistencies over time. Some of those inconsistencies cause immediate problems and fixed. Others just remain there dormant making maintenance increasingly difficult. To rectify the problem, this patch implements ata_port_operations inheritance. To allow LLDs to easily re-use their own ops tables overriding only specific methods, this patch implements poor man's class inheritance. An ops table has ->inherits field which can be set to any ops table as long as it doesn't create a loop. When the host is started, the inheritance chain is followed and any operation which isn't specified is taken from the nearest ancestor which has it specified. This operation is called finalization and done only once per an ops table and the LLD doesn't have to do anything special about it other than making the ops table non-const such that libata can update it. libata provides four base ops tables lower drivers can inherit from - base, sata, pmp, sff and bmdma. To avoid overriding these ops accidentaly, these ops are declared const and LLDs should always inherit these instead of using them directly. After finalization, all the ops table are identical before and after the patch except for setting .irq_handler to ata_interrupt in drivers which didn't use to. The .irq_handler doesn't have any actual effect and the field will soon be removed by later patch. * sata_sx4 is still using old style EH and currently doesn't take advantage of ops inheritance.

* libata: implement and use SHT initializersTejun Heo2008-04-17
| | | | | | | | | | | | | | | | libata lets low level drivers build scsi_host_template and register it to the SCSI layer. This allows low level drivers high level of flexibility but also burdens them with lots of boilerplate entries. This patch implements SHT initializers which can be used to initialize all the boilerplate entries in a sht. Three variants of them are implemented - BASE, BMDMA and NCQ - for different types of drivers. Note that entries can be overriden by putting individual initializers after the helper macro. All sht tables are identical before and after this patch. Signed-off-by: Tejun Heo <htejun@gmail.com>
* libata: PCI device should be powered up before being accessedTejun Heo2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | PCI device should be powered up or powered up before its PCI regsiters are accessed. Although PCI configuration register access is allowed in D3hot, PCI device is free to reset its status when transiting from D3hot to D0 causing configuration data to change. Many libata SFF drivers which use ata_pci_init_one() read and update configuration registers before calling ata_pci_init_one() which enables the PCI device. Also, in resume paths, some drivers access registers without resuming the PCI device. This patch adds a call to pcim_enable_device() in init path if register is accessed before calling ata_pci_init_one() and make resume paths first resume PCI devices, access PCI configuration regiters then resume ATA host. While at it... * cmd640 was strange in that it set ->resume even when CONFIG_PM is not. This is by-product of minimal build fix. Updated. * In cs5530, Don't BUG() on reinit failure.

* libata/pata_it821x: Improve handling of poorly compatible emulationsAlan Cox2008-01-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some it821x RAID firmwares return 0 for the err return off both devices. A similar issue occurs with the slave returning 0 not 1 if you plug a gigabyte sata ramdisk into a controller that fakes two SATA ports as master/slave on an SFF channel. The patch does the following - Allow the 'failed diagnostics' case on both master and slave - Move the HORKAGE_DIAGNOSTIC check after ->dev_config This second change also allows IT821x to fix up a problem where we report drive diagnostic failures when in fact the drive is fine but the microcontroller firmware doesn't appear to get it right. IT821x clears the flag again to avoid giving the user bogus warnings about their disk. The other IT821x change is a bit ugly, we slightly abuse the cable type hook to fiddle with the identify data for the devices. We could add a new hook for this but as we have only one offender and no more seeming likely it seems better to keep libata-core clean. Please let this sit in -mm briefly, just in case the relaxed checking breaks some other emulated interface. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

* libata-link: introduce ata_linkTejun Heo2007-10-12
| | | | | | | | | | | | | | | | | | | Introduce ata_link. It abstracts PHY and sits between ata_port and ata_device. This new level of abstraction is necessary to support SATA Port Multiplier, which basically adds a bunch of links (PHYs) to a ATA host port. Fields related to command execution, spd_limit and EH are per-link and thus moved to ata_link. This patch only defines the host link. Multiple link handling will be added later. Also, a lot of ap->link derefences are added but many of them will be removed as each part is converted to deal directly with ata_link instead of ata_port. This patch introduces no behavior change.

* PCI: Change all drivers to use pci_device->revisionAuke Kok2007-07-11
| | | | | | | | | | | | | | | | | | | | Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

* libata: clean up SFF init messTejun Heo2007-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The intention of using port_mask in SFF init helpers was to eventually support exoctic configurations such as combination of legacy and native port on the same controller. This never became actually necessary and the related code always has been subtly broken one way or the other. Now that new init model is in place, there is no reason to make common helpers capable of handling all corner cases. Exotic cases can simply dealt within LLDs as necessary. This patch removes port_mask handling in SFF init helpers. SFF init helpers don't take n_ports argument and interpret it into port_mask anymore. All information is carried via port_info. n_ports argument is dropped and always two ports are allocated. LLD can tell SFF to skip certain port by marking it dummy. Note that SFF code has been treating unuvailable ports this way for a long time until recent breakage fix from Linus and is consistent with how other drivers handle with unavailable ports. This fixes 1-port legacy host handling still broken after the recent native mode fix and simplifies SFF init logic. The following changes are made... * ata_pci_init_native_host() and ata_init_legacy_host() both now try to initialized whatever they can and mark failed ports dummy. They return 0 if any port is successfully initialized. * ata_pci_prepare_native_host() and ata_pci_init_one() now doesn't take n_ports argument. All info should be specified via port_info array. Always two ports are allocated. * ata_pci_init_bmdma() exported to be used by LLDs in exotic cases. * port_info handling in all LLDs are standardized - all port_info arrays are const stack variable named ppi. Unless the second port is different from the first, its port_info is specified as NULL (tells libata that it's identical to the last non-NULL port_info). * pata_hpt37x/hpt3x2n: don't modify static variable directly. Make an on-stack copy instead as ata_piix does. * pata_uli: It has 4 ports instead of 2. Don't use ata_pci_prepare_native_host(). Allocate the host explicitly and use init helpers. It's simple enough. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.
